Create a Copy of an Existing Component
Components are typically unique and apply only to a particular unit of work. The component’s source contains a unique set of outputs and the component exposes a transformed set of output. However, there are some cases where a component can be applied to numerous data flows with only minor differences. Consider a data warehousing effort that consolidates many sources which contain the same schema. We may want to perform the same transformations on each source. In this use case the ability to copy a component and apply all of the component’s properties to a new data flow is a time saver. The new “Create Copy” feature does exactly that. Here’s how it works.
We will make a copy of the highlighted transformation component in the following example.
Navigate to the detail page of the component that you wish to copy and click the “Create Copy” link that is above the field list.
Provide the name of the new component & click the copy button.
The new component will be created and you will be redirected to the new component’s detail page.
Notice that the new component uses the same source as the old component. The new component also contains all of the old component’s expressions, fields, filters, statistics, and other properties. The new component will not contain any of the dependents that the old component contained.
If you want to use the new component in a new data flow, then use the “Redirect Source” feature which will allow you to map the component’s required inputs to a selected source component.
